Discovery of the New Isotope^(251)Lr

The products of the^(203,205)Ti(^(50)Ti,2n)fusion-evaporation reactions were studied by using the recently commissioned Argonne Gas-Filled Analyzer(AGFA)at Argonne National Laboratory.

^(153)Dy高自旋态的能级结构及缺中子Dy核的形状随中子数与自旋态的变化

通过在束γ谱的实验研究,建立了^(153)Dy的非常高的自旋态的能级图,最高自旋态为81/2.所用核反应为^(122)Sn(^(36)s,5n),束流能量165MeV.在同质异能态(I=47/2)以上,能级结构展示出极端复杂的单粒子跃迁特性.对缺中子Dy核的形状随中子数N及自旋态I变化的系统性进行了讨论.
